Post by z870623 on About CPU Loading ^{CODESYS Forge talk (Post)}
I am running a runtime environment on an ARM A35 dual-core processor (1.5GHz) and have encountered some issues. The CPU load (both CPU0 and CPU1) occasionally spikes above 50% before returning to normal, and this happens around 2-3 times per minute. At the same time, I’ve noticed that the Max Cycle Time in the Codesys monitoring screen shows much worse performance compared to the A53 (1.2GHz), with nearly double the cycle time. The optimizations I have made so far are as follows: Set the CPU to performance mode. Isolated CPUs: CPU0 is dedicated to running Linux services and the runtime itself, while CPU1 runs the EtherCAT task and the MainTask. Despite CPU1 only running these two tasks, the utilization still increases above 50%, which I find unreasonable. Additionally, I performed tests using cyclictest both without and with the runtime running. The performance is shown in the following image: From the results, I believe the CPU performance should be fine, but I am unsure why the monitoring results are not as expected. The testing outcomes should ideally be as close as possible to the cyclictest results. Does anyone have related solutions to this issue?

Post by edvard-munch on How I can get "Done flag" for "Modbus Slave Channel"? ^{CODESYS Forge talk (Post)}
This is from 10 years ago, I know. But I have been using (SLAVE_DEVICE.iChannelIndex = CHANNEL_NUMBER) AND (SLAVE_DEVICE.xDone) I suppose that it shows xDone for the channel that shows up in the iChannelIndex at the same cycle? It seems to be working properly for two devices that I have been using it before But now I have another device and using two write channels, for one register each. One channel works properly and returns DONE flag When another channel is triggered, I see that it shows up in iChannelIndex, but flag DONE not received, but no Error for the channel. Also, when i check the register in the device it's evident that data has been transferred. Is this could happen sometimes with CODESYS, so DONE flag not received? Or this is a problem with a given device? With this certain register

Post by imdatatas on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, I have experienced such situations with some servo drive devices in the past. The home completion information is reported to the upper controller by the slave drive with the states of the relevant bits in the StatusWord (for example; 6041h Bit10, Bit12 in Home mode). If the states of these bits are correct in terms of number and state but the motor does not actually perform the action; You can contact the slave drive manufacturer. There may be a problem with the device firmware. Another area you can play around with is looking at the settings in the "Advanced configuration" for Softmotion axis on the page the link to below, and trying it out and using the one that works for you. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cmd_add_softmotion_cia402_axis.html A method I recommended worked for a user as in below message. https://forge.codesys.com/forge/talk/Engineering/thread/40bc82454d/ I hope your problem will be solved as soon as possible and by sharing the result here, you will help others to know and overcome it. Good luck. Best regards, Imdat

Post by pikebuster on Help for a newbie ^{CODESYS Forge talk (Post)}
Can somebody help me with this? I have problem with the button! This task must be solved using Sequential Function Chart (SFC), IEC 61131-3. TASK Create an SFC program to control a traffic light at an intersection. Description: You will program a traffic light that has three phases: Green, Yellow, and Red. The traffic light must follow these rules: Green light is on for 10 seconds. Yellow light is on for 3 seconds. Red light is on for 10 seconds. If the pedestrian button is pressed, the system must keep the red light on for 20 seconds during the next cycle. After the pedestrian has “crossed,” the system should return to its normal cycle. Basic Steps: Initialization: Start by setting the traffic light to Red. Green Phase: After 10 seconds, switch to Green. Yellow Phase: After 10 seconds in the Green phase, switch to Yellow. Red Phase: After 3 seconds in the Yellow phase, switch back to Red. Loop: Repeat the cycle. Use, for example, lamp symbols in the visualization module to simulate the traffic light. You may also add a simple pedestrian light if desired.

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Back in november I paused this, but wanted to reattempt using the persistent manager, the behavior is still the same. Most "login attempts" s are stopped with the message "One or more errors occurred" but I have no idea what that error might be. The only clue is this message is presented while the lower left status box says "Generating code...: relocation pou". For clarification. Build/Generate code is successful, no errors. Error appears when I try to download/login (physical or simulation) to a device. I did manage to login (in simulation mode) at one point, but then the error message "PersistenceChannel: Config file not found!". And no persistence files were created. I have done device-tree/reset-orgin also clean/clean all etc. Removed/re-inserted persistance manager. Behaviour is just the same. Removing Persistence Manage and everything is working OK. Is there possibly more info somewhere about the "One or more errors occured"-message?

Post by drbuzz on Communication Error (#0) for IFM controller ^{CODESYS Forge talk (Post)}
Hi Folks, Every time I use an IFM controller I always seem to run into a problem connecting to it. I get the Communications Error (#0). So I thought I would share some tips and tricks. Once the CANfox Cable (EC2112) cable driver is installed, you can use the yellow app in the sys tray to blink the lights on the cable. Confirm the cable works in the IFM maintenance software by connecting to the controller and reading the information on it. Make sure to download an OS into the controller (the light will go from a fast blink to solid green). In Codesys V2.3, the communication settings for the CR0401 is 250kBaud by default and Node ID 127. What got me, was I needed to reboot the computer after the cable driver install. Also if your application has canbus settings in it which are changed from default, after the controller is power cycled, the new Node ID and Baud will be in effect. I made a handy guide because too much time has been wasted on this. Programming IFM CR0401 Serial/Can Programming Cable • Connect IFM EC2112 CanFox programming cable with connector adapter. • Make sure cable is linked to VM (if using VM). • Install drivers for cable if not installed. o Download from IFM EC2112 site. https://www.ifm.com/ca/en/product/EC2112 • Once Installed, reboot computer. • In system tray, there should be a yellow icon that you can open and check on programming cable. Select the cable in the list and flash the lights to confirm it is working. Maintenance Software • Install IFM Maintenance Tool Software. o Download from IFM Site. https://www.ifm.com/ca/en/download/eco100_MaintenanceTool • Open IFM Maintenance software • Select Basic System • Select CAN cable • It will tell you if you don’t have a cable connected. • Use Wizard if needed. • Read Channel Parameter on the Settings page, or get Identity in the System Information > Identity. • Default Node is 127 on a new unit. Baud is 250kBaud (bits/sec) • Controller information should populate. • Controller green light should be blinking at 5hz (meaning OK but no OS, just bootloader). • Click Software > Load. • Open the OS file. Should match Codesys version selection (for CR0401 this is version 3). o Download OS file from IFM Website. https://www.ifm.com/ca/en/product/CR0401 o It is located at the top of the download under “software for CR0401”. o Select the file and load it… this will take a minute. • Once completed the unit should now have a solid green light o Solid green means the controller has an OS but no application is running. Codesys V2.3 Application • Codesys needs to be downloaded and installed from the IFM website as it has the IFM libraries and license to use the software. o Download from the IFM CR0401 page. o https://www.ifm.com/ca/en/product/CR0401 • Create new application with the correct IFM controller or Open Codesys application. • Keep in mind that the PLC Configuration on the Resources tab can be changed for the CAN communication interface… so changes to node and baud will take effect after the first download and reboot of the controller. • Go to “Online” in the top menu and change “Communication Parameters” o The Local dropdown shows the last configuration used. All other interfaces will show below it and need to be updated when changed or used. o Confirm Node ID is 127 for the first download.  The NodeID will change to whatever the program has after (in my case 125).  Node Send Offset should be default at 1536  Node Recv Offset should be default at 1408  Can bus Baudrate should be 250 kbaud.  Yes to Motorola Byte Order  Block Transfer should be false and note used (60 is default setting).  Can Card Driver should match the systray item which is Sie_USB. • If the system populated the other one, just update and relay the communication parameters. The software will usually bring up the available cable and driver. • Go to “Online” and Login to download. o Press Yes to Download Application. I hope this helps!

Post by razebones on sdo read write codesys 3.5 ^{CODESYS Forge talk (Post)}
ENG For some reason, I can't bind a variable to the data parameter. Also, why does only the sdo_read4 function work for me? I also can't write through sdo_write4. I can only view the received values via sdo_read4. Please help me with this task. Moreover, I tried to write the values through sdo write 4 and for a while the data stopped being written and I overwritten it manually and sdo read4 started working again and at the same time they do not want to work in the main task. RU Я не могу почему то привязать переменную к параметру data. Так же у меня почему работает только функция sdo_read4 так же не могу записать через sdo_write4. Могу только просматривать полученные значения через sdo_read4. Помогите пожалуйста с этой задачей. Причём я попытался записать значения через sdo write 4 и у меня на какое то время перестали записываться данные и перезаписал вручную и sdo read4 начал работать снова и одновременно они не хотят работать в main task.

Post by mondinmr on Unexpected behavior in cyclic encoder read method during INT overflow (wrap-around) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m investigating a potential issue with a cyclic method we use for reading incremental encoders in our libraries. I’ve come across two implementations that, at first glance, appear to perform the same operation: motionUnit.vlPositionActualValue is UINT due strange encoder type. Version A METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; rI: INT; delta: INT; END_VAR rI := TO_INT(motionUnit.vlPositionActualValue); delta := rI - actPosFieldOld; m_actPosRaw := m_actPosRaw + TO_LREAL(delta); actPosFieldOld := rI; IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Version B METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; END_VAR m_actPosRaw := m_actPosRaw + TO_LREAL(TO_INT(motionUnit.vlPositionActualValue) - actPosFieldOld); actPosFieldOld := TO_INT(motionUnit.vlPositionActualValue); IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Both use INT and the same delta logic, so they seem equivalent. However, when an overflow (wrap-around) occurs, version A continues correctly as expected, while version B unexpectedly resets to -32768 without a clear reason. Has anyone experienced similar behavior or can shed light on what might be happening here? It almost seems as if the cast to LREAL is being applied before the calculation — but that would be illogical and potentially very dangerous in many situations! Thanks!

Post by abuckie on i2c master not running ^{CODESYS Forge talk (Post)}
Hello, I am trying to create an Ethernet/IP device that can read analog signals, do some basic logic on it and then hand communicate the results to an Ethernet/IP master. I am using the Raspberry Pi to experiment with this as I would ultimately like to drive a display as well. I have loaded up the runtime on the Pi and got the digital I/O working. I have an ADS1115 ADC to I2C board and I can't get it to work, I get a message telling me the i2c master is not running and I am not sure where to start with this. Is there a manual for running CODESYS on the Pi or something like that I am missing? I found this post and opening the project in CODESYS V3.5 SP21 it seems like tons of this wouldn't convert properly https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/ I have added in the library and device manually and copied the structured text program but lost at what to do if the core functionality of the master is not running. I appreciate any help, thanks.

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Web Client Library Documentation Company: 3S - Smart Software Solutions GmbH Title: Web Client Version: 1.0.1.7 Categories: Application|Utils Namespace: WEB_CLIENT Author: 3S - Smart Software Solutions GmbH Placeholder: WebClient I encountered an issue using this library above. Note it is now part of Codesys IIoT Libraries SL in the form of Web Client SL, but I am not using this version. I was sending Content-Type: application/json, HTTP POST using a HTTPS URL. No issue observed initially, successful operation. At some point operation stopped and the codesyscontrol.log file started to accumulate errors: ERROR: TlsCreateContext2: Failed to save context. An application reset failed to resume operation and I was unable observe any TCP connection forming to a destination port 443. The error appeared as a TCP_INIT error. I can find no details as to what may have happened or why a reset of the PLC application did not resume operation. Testing with a curl operation proved to be successful, so I am confident there was no fundamental networking issue preventing a TCP connection forming. The solution was to reboot the hardware itself, but this is not satisfactory in the long term. Is there any description of the TLS error I received? Is there any suggestion here that there might be an issue with certificates? Any advice or information is appreciated.

Post by westcountryewe on Displaying a Target Web Page on WebVisu ^{CODESYS Forge talk (Post)}
I have a main PLC with my CODESYS project on, including Web Visu. I also have a second device used for pump monitoring, all of this is displayed on a seperate HMI. I am looking at displaying the pump monitoring HMI on WebVisu so that I can solely use 1 HMI rather than having two. I can project the pump monitoring HMI into Chrome, and log in and it works fine. When I'm using the Web Browser element in Web Visu, enter my URL (device IP) it shows me the web page, but doesn't show me all of it. It uses parts of JavaScript for the login authenticiation and various other widgets. Similarly, I cannot get Youtube or Google to display on WebVisu either (possibily because of the same reason). Does anybody have any tips on how I can display the likes of Youtube or Google onto WebVisu so I can view it on my 7inch HMI (I suspect that if I can get Youtube or Google to work, then I will also be able to get my pump montitoring web page to work too).

Do you need an 'hours-run' counter? And 1 second resolution is ok? I think you're over-thinking it. (The task time needs to be < 1second) Have a look at the LAD...

Post by dhumphries on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
I'm working on a low cost project and I'm considering installing the Codesys runtime on a PC running Linux Debian instead of buying a PLC with a pre-installed runtime. For my needs the Control Standard S license should be capable of running some IO over ethernet/ip, and a webvisu. The PC I am considering has a AMD GX-424CC 2.4GHz processor (4 core/4 thread) and 4GB RAM. This may compare to a raspberry pi4, but I know an X86 processor doesn't directly compare to an ARM processor, and a processor can have a high clock speed but other factors like L2/L3 cache can influence the overall performance. I can't find any published specs for the processor and RAM requirements to run the Codesys Control runtime, does anybody have a link to the minimum system requirements or experience using devices that are at or below the minimum system requirements. A raspberry pi with the control for raspberry pi SL runtime license would be the lowest cost option, but the license is not for commerical use. This restriction is somewhat vague, can anybody clarify if this means I can use a raspberry Pi runtime for in-house automation, what about if I am selling an integrated system that uses a raspberry Pi as a controller?

Post by forest on SM Drive license error ^{CODESYS Forge talk (Post)}
Hi, when it comes about license, I used INVTmatic Studio, which uses Codesys, for programming INVT plc. I bought Codesys Modbus license, it was not expensive, and then realised that INVT didn't have License Manager option (greyed out in program) which is needed for using of Codesys License. I contacted support from INVT, but developers told me that option is still not available. So depending on environment for programming Codesys, you can or not use Modbus license. Good thing about this version of Modbus TCP it works both direction. I could send commands and receive feedbacks from drive. But communication stops after 30 mins. So I used simple version of ethernet modbus which is somewhere in INVT or Condesys library (I can check tomorrow) which works only one way. I could send cmd to drive, and control it, but didn't have any feedback, like some readings back in PLC. which is bad, but at least I could start it and it didn't fail after 30 mins.

Post by wbj0t on System libs and I/O Drivers ^{CODESYS Forge talk (Post)}
Hi everyone. My question about: where I can learn (read or watch) an info about codesys workflow through the system IO libs? I want to know how to implement I/O drivers by my self. In the system libs I see many interfaces, methods etc... But there is no explanation about them, just names of methods and fields of the FBs. I know about this page: https://forge.codesys.com/drv/io-drivers/doc/Generic/ There is so BIG the device description file and not so clear explaining of the attributes and elements, also some elements or attributes missed at it all. Yes, there are code examples on this page, but, so shortly and, for example, code about Modbus drivers is absent. And even if I try to add the IoDrvFB with lib, I get and error, something like: "failed to load IoDrvFB driver". And what about the book of codesys that written by Gary Pratt? Is there information about system libs and drivers in this book more clearly? Thank you :)

Post by fredsta on Unable to load dynamic modules (Download failed: Application=Application) ^{CODESYS Forge talk (Post)}
Hey there, I am currently trying to find a good solution for the communication between CODESYS Control on Raspberry Pi and "the rest of the world", i. e. the things apart from CODESYS on my linux. My first approach was to use the c-integration. So I created a lib, defined extern fbs, compiled the code on my Pi using the SDK and put the .so into my lib project. When I try to log into the Pi and load the program, I get the error message which you can see in the attached picture. "Die dynamischen Module der C-Integration konnten nicht auf das Laufzeitsystem geladen werden" is german and means roughly "the modules from the c-integration could not be loaded onto the runtime system." Is this normal? Am I doing something wrong? I will have a look at the unix domain socket thing next, as I am still in the process of finding the best solution for the communication.

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
I am trying to implement a mechanism to send alarm SMS. For this, I have created an Alarm Class with a Notification Action which calls a POU. This POU implements IAlarmNotifiable making it selectable in the Alarm Class configuration. IAlarmNotifiable has an Execute method which is called by the alarm class. Now, I want to extract the alarm message of the triggered alarm. The Execute method comes with a VAR_INPUT itfAlarm: AlarmManager.IAlarm which supplies a method called GetMessage. The help text says: Returns the message text, that has been configured for the alarm. The result is a pointer to the buffer, where the message text is stored The type of the result is CharBufferPtr, and at some place I read that it can be interpreted as a pointer to string. But I cannot manage to extract the alarm message, all I get are numbers. I have tried the following: psAlarmText := itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^; sAlarmText := TO_STRING( itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^ ); So how do I get access to the alarm message as clear text? (In this case, "Larm 1")

Post by tim-roelant on Profinet fault with codesys control V3 - Receive packet error ^{CODESYS Forge talk (Post)}
I have set up a brandnew Beckhoff panel pc with a codesys control runtime V3. I configured it together with 2 profinet field devices: a 16in/16out IO module from Turck and an MTS linear encoder. The machine works fine untill all of a sudden the communication breaks and the profinet participants become unreachable. At that point I can still ping the device, but the profinet master does not find them anymore: When i do a scan they are not found. When i do a cold restart, the profinet master becomes active again and the devices are found again. In the log i get Ethercat packet receive error: sysethernet. I am a little confused, there is no ethercat device in the device tree. I already set the send clock and the reduction ratio to higher values, but without result. Can codesys be configured, so that the communication re-establishes without doing the cold reset? This is very annoying and is causing a lot of prodution losses. regards Tim
